JPL Horizons On-Line Ephemeris System provides access to key Solar System data and flexible production of highly accurate ephemerides for Solar System objects. Osculating elements at a given epoch (such as produced by the JPL Small-Body Database ) are always an approximation to an object's orbit (i.e. an unperturbed conic orbit or a " two-body ...
JPL Horizons On-Line Ephemeris System, maintained by the Solar System Dynamics Group at the Jet Propulsion Laboratory, provides ephemeris for asteroids, comets, planets, moons, solar system planets, the Sun, and some spacecraft.

There have been many versions of the JPL DE, from the 1960s through the present, [2] in support of both robotic and crewed [3] spacecraft missions. Available documentation is limited, but we know DE69 was announced in 1969 to be the third release of the JPL Ephemeris Tapes, and was a special purpose, short-duration ephemeris.
The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies.It is maintained by Jet Propulsion Laboratory (JPL) and NASA and provides data for all known asteroids and several comets, including orbital parameters and diagrams, physical diagrams, close approach details, radar astrometry, discovery circumstances, alternate designations and lists of publications ...
The orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch after leaving the planetary region and is calculated with respect to the center of mass of the Solar System. Inbound JPL Horizons shows an epoch 1950 barycentric orbital period of 2.2 millions years with aphelion of 34,000 AU (0.5 ly) from ...
3.3 (assumed) [3 (55565) 2002 AW 197 ( provisional designation 2002 AW 197 ) is a classical, non-resonant trans-Neptunian object from the Kuiper belt in the outermost region of the Solar System , also known as a cubewano .
Its orbit is well determined; as of 11 January 2017 its orbital solution is based on 34 observations spanning a data-arc of 5821 days. [3] Alicanto's orbit is similar to that of 2013 RF 98 , indicating that they may have both been thrown onto the orbit by the same body, or that they may have been the same object (single or binary) at one point.
Official naming citations of newly named small Solar System bodies are approved and published in a bulletin by IAU's Working Group for Small Bodies Nomenclature (WGSBN). [1] Before May 2021, citations were published in MPC's Minor Planet Circulars for many decades. [2] Recent citations can also be found on the JPL Small-Body Database (SBDB). [3]
